Apparatus for winding yarn

ABSTRACT

A YARN WINDING APPARATUS OF THE TYPE THAT PROVIDES FOR AUTOMATICALLY TRANSFERRING WINDING ACTION FROM A FULL TO AN EMPTY YARN PACKAGE SUPPORT WITHOUT WASTE IS MODIFIED BY THE ADDITION OF A DEVICE TO PROVIDE STORAGE AND RELEASE OF MECHANICAL TORQUE TO ASSIST IN ROTATING A PIVOTALLY MOUNTED ARM CARRYING THE PACKAGE SUPPORTS. THE WINDING APPARATUS INCLUDES A FRAME, A PAIR OF PACKAGE SUPPORTS ALTERNATELY MOVABLE INTO SURFACE DRIVEN ENGAGEMENT WITH A DRIVE ROLL AND AN ARM PIVOTALLY MOUNTED BETWEEN ITS ENDS TO A LINKAGE MECHANISM CONNECTED TO   THE FRAME. THE SUPPORTS ARE CARRIED BY CHUCKS ROTATABLY MOUNTED AT OPPOSITE ENDS OF THE ARM. A CAM KEYED TO THE ARM AT ITS PIVOT POINT ENGAGE A SPRING-BACKED CAM FOLLOWER MOUNTED TO THE LINKAGE MECHANISM FOR STORING AND TRANSMITTING MECHANCIAL TORQUE TO ASSIST IN PIVOTING THE ARM.

Filed Mar. 31, 1971, Ser. No. 129,820 Int. Cl. Bosh 54/02 US. Cl. 242-18 A 4 Sheets Drawing. 10 Pages Specification A yarn winding apparatus of the type that provides for automatically transferring winding action from a full to an empty yarn package support without waste is modified by the addition of a device to provide storage and release of mechanical torque to assist in rotating a pivotally mounted arm carrying the package supports. The winding apparatus includes a frame, a pair of package supports alternately movable into surface driven engagement with a drive roll and an arm pivotally mounted between its ends to a linkage mechanism connected to the frame. The supports are carried by chucks rotatably mounted at opposite ends of the arm. A cam keyed to the arm at its pivot point engages a spring-backed cam follower mounted to the linkage mechanism for storing and transmitting mechanical torque to assist in pivoting the arm.
